Academic publishing is a painfully slow process, especially compared to everyday online communication. But there's something to be said for carefully designed, peer-reviewed work in the conversation on blogging and public relations. (And thanks to Constantin Basturea for saying something.)
"Organizational blogs and the human voice," though only a small first step, is now up in Journal of Computer-Mediated Communication, 11 (2). I've got another study under way in this same line of research. The next one builds on the experimental study just posted, with a broader sample from the "real world" of organizational/corporate bloggers.
The new study is an online survey, and there's an outside chance that if you're reading this, you might be part of the sample, so I probably ought not to make too much of it here. Shel Holtz recently made an interesting point about sampling issues with online surveys about blogging.
